Guilt is a learned behavior, and we ACoA have it in spades. We'd all make wonderful Catholics. I will tell you that I didn't just cut the cord and then go do cartwheels shouting "Free at last, free at last. Lord Almighty I'm free at last!" What I *did* do was haul my butt to Al-Anon and threw myself headfirst into a program. I still get the well-intentioned guilt trips from strangers or extended family who have no effing clue what's been going on for the past 30-something years. I just tell them that my mother is an alcoholic and it's in my best interest to not speak to her. If they continue to prod, I either hang up or walk away. Not much I could tell them that would do any good.
These things take time. Just know that you are doing the right thing and what anyone else thinks of you is none of your business.
